  1.

    巫溪縣紅池壩地區由於歷史上開發強度和生態恢復措施的不同，使當地植被形成了從草本群落灌木灌叢林灌過渡帶日本落葉松（ larixdaempferi ）針葉純林華山松（ pinusarmandii ）針闊葉混交林天然闊葉落葉林的一系列生態恢復演替階段。
  3. The vegetation types are described of baishanzu national nature reserve in qingyuan county, zhejiang province. the surveyed area covered25thousand hm 2 in which27sample plots with20m 20m each were selected. based on the importance value of plant species, six vegetation types were devided, viz. evergreen broadleaved forest, evergreen and deciduous broadleaved mixed forest, coniferous and broadleaved mixed forest, coniferous forest, mountain dwarf forest, and mountain shrub and herbosa. floristic composition, community structure, and trend of community succession of each vegetation type are described

    對近20年來多次調查的資料進行系統整理，將百山祖植被主要劃分成6個植被類型:常綠闊葉林、常綠落葉闊葉混交林、針闊葉混交林、針葉林、山地矮林和山地灌草叢，其下可分為22個群系;同時對群落的種類組成、結構和演替趨勢作了概述。
